Feminine gender identity and physical aggressiveness in heterosexual and homosexual pedophiles
Abstract:
This study explored the differences among six groups of adult males in retrospective self-reports of childhood gender identity and physical aggressiveness. The three groups of homosexual men preferred prepubescent, pubescent, or physically mature sexual partners. The three groups of heterosexual men preferred prepubescent partners, normal sexual interaction with physically mature partners (controls), or anomalous interaction with physically mature partners. Childhood gender identity was measured with the Feminine Gender Identity Scale (FGIS), and boyhood aggressiveness was measured with the Physical Aggressiveness Scale (PAS). Duncan tests at the .05 level showed that the FGIS differentiated the homosexuals who preferred mature partners from the five other groups; whereas the PAS differentiated all homosexual groups from all heterosexual groups. These results suggest that male homosexuals in general tend to be unaggressive in boyhood, whereas only those who prefer mature sexual partners show significant levels of feminine identification.
